Problem 1
What is the wavelength (in \(\mathrm{mm}\) ) of light if its frequency is \(1.55 \times 10^{10} \mathrm{~s}^{-1}\) ?
Problem 2
Calculate the frequency of radiation if its wavelength is \(988 \mathrm{~nm}\). Where does this radiation appear in the electromagnetic spectrum?
Problem 4
You are exposed to radiation that has a wavelength of \(50 \mu \mathrm{m}\). What is the frequency of this radiation? Where does this radiation appear? Is this radiation ionizing or nonionizing?
Problem 6
How can you alter a house that tests over the \(4 \mathrm{pCi}\) level for radon?
Problem 7
Give one crazy application of x-ray science.
Problem 8
Which is the heaviest form of radiation: alpha, beta, or gamma?
Problem 9
Which is the heaviest form of radiation: alpha, beta, or gamma?
Problem 11
Fatman (Nagasaki bomb) used approximately \(6.4 \mathrm{~kg}\) of Pu-239. This artificially produced isotope \(\left(\mathrm{t}_{1 / 2}=24,100\right.\) years) undergoes alpha decay. How many kg and pounds would remain after three decay processes?
Problem 13
The \(t_{1 / 2}\) of As-74 is 18 days, how much of a \(160 \mathrm{mg}\) sample remains after 2160 hours?
Problem 14
Write a balance reaction for the decay Ir-192. This isotope undergoes alpha and gamma emission at the same time.
